Description

[Detailed Description of the Invention] The present invention relates to a shutter, and its purpose is to provide a shutter that has a strong structure and is easy to manufacture and assemble.

Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. 1 is a pair of guide rails installed on both sides of the entrance of a house, 2 is a rotating shaft installed above the guide rails 1, not shown. It is rotated forward and reverse by the drive device.

3 shows the entire shutter with both side edges slidingly engaged with the guide rail 1 and the upper edge attached to the rotating shaft 2;
Reference numeral 4 denotes a bag-shaped first slat composing the shutter 3, which has a cylindrical hook portion 4a formed at its upper end, and has a lower support surface 4b raised by a certain height.
On the other hand, as shown in FIG. 2, through holes 4c are provided at equal intervals.

Although the first slat 4 is made of a single thin plate as shown in FIG. 2, it may also be extruded from aluminum or synthetic resin.

Reference numeral 5 denotes a second slat composed of a connecting rod 6 in the shape of an elongated square column and a plurality of supporting plates 7 connected and suspended from the connecting rod 6 at equal intervals. A cylindrical hook portion 7a on which the hook portion 4a of one slat 4 can be hooked is formed.

Now, in order to connect the second slat 5 to the first slat 4, move the second slat 5 in the direction of the arrow in FIG. All you have to do is insert it into the hole and protrude it downward.

Also, the lower end hook part of this second slat 5? Another first slat 4 is hooked to a as shown in FIG. 3a.

FIG. 1a shows the state in which the shutter 3 is rolled up and the entrance/exit is opened.

In this state, when the shutter 3 is rewound, the
As shown in FIG.
is lowered along the guide rail 1 in an open state (a state in which the window hole W formed between the support plates 7 of the second slat 5 is visible).

When the lowermost end of the shutter 3 contacts the ground, the entrance is closed as shown in Figure 1, but the -1st Nislats 4 and 5 remain open due to their own weight.

When the shutter 3 is stopped at this position, the second Nisrat 5
The window hole W allows daylighting, ventilation, and visibility into the interior and exterior, and serves as a security measure.

Furthermore, when the shutter 3 is rewound, the open first and second slats 4 and 5 descend due to their own weight, and the second slat 5 enters the first slat 4, as shown in FIG. The lower end edge contacts the upper edge of another first slat 4 located below, and both slats 4 and 5 are in a closed state.

(See FIG. 1C) Now, in the embodiment of the present invention, a support surface 4b is integrally formed at the lower part of the first slat 4, and an insertion hole 4C is provided in the support surface 4b, so that the support surface of the second slat 5 is 7 is inserted to lock the connecting rod 6 to the support surface 4b, the cross section of the first slat 4 becomes an S゛ square shape, and its strength can be increased. To attach the second slat 5, it is sufficient to insert the second slat 5 into the first slat 4 from the side and insert its support plate 7 into the insertion hole 4C. The shutter 3 can be easily assembled by connecting the hook portions 4a and 7a in multiple stages vertically.

As described above, this invention makes it possible to attach the second slat 5 to the first slat 4 extremely easily, and also to attach both of these slats 4 and 5 to their hook portions 4a and 7a.
This provides an excellent effect in that the shutter 3 can be easily assembled by connecting multiple stages vertically.
